Download or read book Mercury from Gold and Silver Mining written by Luiz D.de Lacerda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.
Download or read book Mercury Mining and Empire written by Nicholas A. Robins and published by Indiana University Press. This book was released on 2011-07-25 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the basis of an examination of the colonial mercury and silver production processes and related labor systems, Mercury, Mining, and Empire explores the effects of mercury pollution in colonial Huancavelica, Peru, and Potosí, in present-day Bolivia. The book presents a multifaceted and interwoven tale of what colonial exploitation of indigenous peoples and resources left in its wake. It is a socio-ecological history that explores the toxic interrelationships between mercury and silver production, urban environments, and the people who lived and worked in them. Nicholas A. Robins tells the story of how native peoples in the region were conscripted into the noxious ranks of foot soldiers of proto-globalism, and how their fate, and that of their communities, was—and still is—chained to it.
Download or read book Mercury and the Making of California written by Andrew Scott Johnston and published by University Press of Colorado. This book was released on 2013-09-15 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the development of California and the relationship between the built environments of the mercury-mining industry and the emerging ethnic identities and communities in California, Mercury and the Making of California brings mercury to its rightful place alongside gold and silver in their defining roles in the development of the American West. In this pioneering study, Andrew Johnston examines the history of California’s mercury-mining industry—and its defining role in the development of the American West. Mercury was crucial to refining gold and silver; therefore, its production and use were vital to creating and securing power and wealth in the west. The first industrialized mining in California, mercury mining had its own particular organization and structure shaped by powers first formed within the Spanish Empire, transformed by British imperial ambitions, and manipulated by groups made wealthy and powerful by controlling it. In addition, the landscapes of work and camp and the relations among the many groups—Mexicans, Chileans, Spanish, British, Irish, Cornish, American, and Chinese—throughout the industry’s history illustrate the complex history of race and ethnicity in the American West. Combining rich documentary sources with a close examination of the existing physical landscape, Andrew Johnston explores both the detail of everyday work and life in the mines and the larger economic and social structures in which mercury mining was enmeshed, revealing the significance of mercury mining to Western history.

Download or read book Shifting Livelihoods written by Daniel Tubb and published by University of Washington Press. This book was released on 2020-06-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honorable Mention for the Society for the Anthropology of Work (SAW) Book Prize The many dimensions of gold in a shadow economy People employ various methods to extract gold in the rainforests of the Chocó, in northwest Colombia: Rural Afro-Colombian artisanal miners work hillsides with hand tools or dredge mud from river bottoms. Migrant miners level the landscape with excavators, then trap gold with mercury. Canadian mining companies prospect for open-pit mega-mines. Drug traffickers launder cocaine profits by smuggling gold into Colombia and claiming it came from fictitious small-scale mines. Through an ethnography of gold that examines the movement of people, commodities, and capital, Shifting Livelihoods investigates how resource extraction reshapes a place. In the Chocó, gold enables forms of “shift” (rebusque)—a metaphor for the fluid livelihood strategy adopted by forest dwellers and migrant gold miners alike as they seek informal work amid a drug war. Mining’s effects on rural people, corporations, and politics are on view in this fine-grained account of daily life in a regional economy dominated by gold and cocaine.
Download or read book Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems written by St ́ephane Gu ́edron and published by Mdpi AG. This book was released on 2021-11-09 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ''Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems'' endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.
Download or read book Toxicological Effects of Methylmercury written by National Research Council and published by National Academies Press. This book was released on 2000-09-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

Download or read book Quicksilver written by Kenneth Baxter Ragsdale and published by Texas A&M University Press. This book was released on 1976 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before Terlingua achieved some notoriety as the site of the annual World Championship Chili Cookoff, the ghost town was the bustling center of the mercury mining industry in the United States. Quicksilver tells the story of the company town and its feudal lord, Chicago industrialist Howard E. Perry, who built a hilltop mansion overlooking the dry domain. Based on many primary sources, this solidly researched and historically sound book tells of profit, power, and loss; of U.S. Army protection from the effects of revolution south of the border; of Depression-era maneuverings and labor unrest; and of a region that holds growing fascination for thousands of visitors each year. Color and authenticity come from the author's interviews with such individuals as Robert Cartledge, who for nearly three decades worked as store clerk, purchasing agent, and finally general manager of the Chisos Mining Company in Terlingua.
